BARREL-HEAD AND FASTENING.

SPECIFICATION forming pari; of Letters Patent N o. 374,446, datedDecember 6, 1887.

Application filed Scptemhfr 13, [887. Serial No. 249,573.

.T ZZZ whom it may concern:

Be it known that I, ROBERT CONRAD BOEK- LER, of Mankato, in county ofBlue Earth and State ofy Minnesota, have invented a new and usefulImprovement in Barrel-Heads and Fastenings, of which the following isfull, clear, and exact description.

My invention relates to removable heads for barrels and fasteningstherefor, and has for its object-to provide a simple, inexpensive, andefficient barrel-head and fastening, which may readily loe locked airand fluid light in the barrel, which. barrel has a smooth inner facewhere the head fits it, so as not to interfere with the handling orremoval of its contents and allow quick and thorough cleaning.

The invention consists in certain novel features of construction andcombinations of parts of the barrel-head and fastenings, allashercinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part-ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure I is a plan view of a barrel provided with my improved head andfastenings and partly broken away and in section. Fig. 2 is a verticalsection of the barrel, taken on the line w 5v, Fig. I. Fig. 3 is anenlarged detail transverse section taken on the line y y, Fig.

`l; and Fig. 4L presents detail views in plan and sectional sideelevation cfa modified form of plate for holding the cam clamp to thebarrelhead.

The barrel or keg A is built up of staves B, hooped at O, in the usualor any approved way, and is made in oval forni in transverse section.The barrel-staves B are preferably made a little thicker than usual atthe end next the removable head D of the barrel, to allow the inner faceof the staves to be dressed off all around by a shaping-cutter, so astopresent a truly curved and smooth surface on which the packing d of thehead D fits closely, as hereinafter more fully explained. The other orxed head E of the barrel is fitted in a croze cut in the usual way inthe staves, and is provided with-a glass or transparent plate, e, of anydesired size, and fitted to a groove made for it in the head, a rubberor other packing, e', being preferably interposed at the joint of (Nomodel.)

the plate with the head, as shown most clearly in Fig. 2 0f thedrawings.

The removable barrel-head D, to which nly invention specially relates,is made with an outside frame or rim, F, .of wood or metal, which hasthe general oval form of the inside ofthe barrel, and is made alittlesmaller than the opening of the barrel where it is to fit, to allow thepacking eZ ofthe head to be fitted in a groove in the outside edge ofthe frame to bear onto the dressed staves, and at its inner edge thecomparatively narrow frame F is grooved all around to receive a glass orother transparent plate, G, with an interposed packing", as clearlyshown in Fig. 3 of the drawings.

When the frame F is made of wood, I prefer to shape it from a strip ofhard wood, grooved at opposite edges to receive the packings Z g, andthen steam it and bend it around a templet or former to give it thenecessary shape to fit the barrel. The joint of the steamed and bentstrip maybe secured in any approved way.

rlhe head D is held to the barrel by two or more cam-lever clampingdevices, according to the size of barrel. The drawings show four ofthese cam-lever clamps on a barrel of considerable size. These clampsare made alike, and comprise a lever, H, having a cam-head, h, andpivoted at ZL to a link, I, which has at its inner end an eye, t',through which passes loosely the threaded end of an eyebolt, J, on whicha nut, K, is fitted above the eye. The. loop or bent head or eye j ofthe bolt J incloses a cross-bar or staple, Z, of a fasteningplate, L,which is screwed or otherwise fastened at bothl ends to the upper faceof the barrel-head frame F. A modified and insome instances a preferredforni of the fasteningplate, L, is shown in Fig. 4 of the drawings,which shows it provided with a central screw, Z', immediately below thestaple Z, which re` ceives the eye of the bolt J, and when this screw Zis turned fully into the frame F additional screws, Z2, will be screwedthrough holes made in the plate into the barrel-head frame, as willreadily be understood.

As the toe ofthe cani-lever head hwould be liable to indent the endwood-of the barrelst-ave, I let iiush into the stave next the headclampan angular metal plate, M, the outer IOO jecting lip or lug, m2, forminga stop to the to the outside of the barrel.

' the open end et' the barrel, the cam-levers H will be rested by t-heirheads h upon t-he plates part, m, of which iseontined by the adjacentbarrel-hoop C, and the top m of the plate on which the eamzlever bearsis provided at its extremity with a transverse upwardly-prohead of thelever, all as most clearly shown in Fig. 3 ofthe drawings.

To apply the head D to the barrel, two opposite cam-levers, H, willserve as handles by which to hold the head and slip it edgewise into thebarrel, and when the head is drawn up as snugly as possible by the handsacross M, and will be turned down into positions indicated in Figs. l,2, and 8 of the drawings, which will draw the packing d of the head orthe margin of the head, should it have no packing, snugly to the insideof the barrel. By adjusting the nuls K on the screws J any requisitepurchase may be given the levers to assure their effective operation indrawing the head D very tightly to place. lVhen the barrel or keg is tobe used for shipping purposes, the levers H will be helddown to place bystaples orV other locking devices attached The cam-levers may be quicklyturned upward from their locking positionsl to allow removal ofthebarrel-head.

It is obvious that the above described fastening` is verysiniple, cheap,and effective, and that it will hold the removable head tothe barrelwith an air and liquid tight joint, and there is no metal necessarilyexposed to rust or corrode when the barrel is used for pieklingpurposes, and when the head is removed there is no flange, groove, orrabbet left in the bari rel to hinder the free handling` or dischargeot' its contents, or to interfere with a quick and thorough cleaning ofthe barrel.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is"- 1. The combination, with a barrel, ofaremovable headiitted to its inner face and camlevers connected to thehead and adapted to bear 011 the barrel-staves to lock the head in thebarrel, substantially as herein set forth.

2'. The combination, with a barrel, of a removablehead provided with anedge packing and fitted to the inner face of the barrel, and cam-leversconnected to the head and adapted to bear on the barrel-staves to lockthe head in the barrel, substantially as herein set forth.

8. rihe combination, with a barrel, of a removable head fitted to itsinner face, camlevers connected to the head, and metal plates fixed tothe barrel-staves to receive the thrust ofthe levers in locking the headto the barrel, substantially as herein set fort-h.

4t. The combination, with a barrel, of a removable head fitted to itsinner face, eamlevers connected to the head, and inet-al plates M,having angular form and fitted by their parts m beneath the barrel-hoop,and having parts m receiving the thrust of the cam-levers and providedwith stops m2, substantially as herein set forth.

5. The combination, wil-h a barrel, of a removable head fitted to itsinner face, screws J, held to the head, nuts K ou said screws, links l',held to the screws inside of the nuts, and cani-levers H, pivoted to thelinks and adapted lo bear on the stares of the barrel to lock the headthereto, substantially as herein set forth.

6. The combination, with a barrel, of a removable head titted to itsinner face, plates L, held to the head, screws J, hung on the plates,nuts K on said screws, links I, held to the Screws inside of the nuts,and earn-levers H, pivoted to the links and adapted to bear on theslaves of thebarrel tolock the head thereto, substantially as herein setforth.
